RIVER - LANDFORMS

V- SHAPED VALLEY

V-SHAPED VALLEYInclined surface on the side of the river.

Down cutting is faster than lateral cutting due of depth of river.

Eg:- Grand canyon created by Colorado river, USA.

GRAND CANYON- COLORADO RIVER

WATER FALL

•Vertically downfall of water from steep places

•Biggest waterfall in India “jog waterfall” in Karnataka

Waterfall

FLOOD PLAINS

Deposit of silt in river banks

Mostly during river overflows

Fertile lands for cultivation Eg:- great Indian plains

MEANDERSRiver flow zig-zag manner

Due to less speed of flow along plain region.

Curve of meander isolated known as Ox-bow Lake.

MEANDERS

DELTADerived from Greek letter Delta

Deposits seen in mouth of river.

Last landforms created by river.

CONCLUSION

Running water creates several landforms in earth from its beginning to end . They are V-shaped valley, waterfall, meander, floodplains, delta.
